Fading AGNs in Poststarburst Galaxies

The Astrophysical Journal, 2023
The role of active galactic nuclei (AGNs) in quenching galaxies and driving the evolution from star forming to quiescence remains a key question in galaxy evolution.

The State of the Molecular Gas in Post-starburst Galaxies

The Astrophysical Journal, 2023
The molecular gas in galaxies traces both the fuel for star formation and the processes that can enhance or suppress star formation. Observations of the molecular gas state can thus point to when and why galaxies stop forming stars.

E+A Galaxies in and Around Nearby Rich Clusters of Galaxies

Research Notes of the AAS, 2021
Abstract We have spectroscopically identified 600 new E+A galaxies and candidates across 16 fields totaling roughly 480 square degrees in the Sloan Digital Sky Survey. E+A galaxies are post-starburst systems that have undergone a significant burst of star formation within the past 1–2 Gyr and are now fully quenched. They comprise a small

DESI Survey Validation Spectra Reveal an Increasing Fraction of Recently Quenched Galaxies at z ∼ 1

The Astrophysical Journal Letters, 2023
We utilize ∼17,000 bright luminous red galaxies (LRGs) from the novel Dark Energy Spectroscopic Instrument Survey Validation spectroscopic sample, leveraging its deep (∼2.5 hr galaxy ^−1 exposure time) spectra to characterize the contribution of recently

Families of galaxies in the  e-Re plane [PDF]

Monthly Notices of the Royal Astronomical Society, 1992
Using a complete sample of Virgo cluster galaxies and a larger set of heterogeneous literature data, we show that ellipticals, early-type dwarfs, and bulges of S0s and of spirals form two distinct families in the plane of the effective parameters, R e and μ e . The «ordinary» family is composed of all galaxies fainter than M B ≃−19.3.
